Repeated Motor Over Peak Current alert

<< < (2/4) > >>

Alan:
Easy enough to find out for sure. Take out the KA altogether and run the loco.

ON28:
To the surprise of no one, the loco seems to function well without the KA. However, when I reset voltage it maxed out at 770 mAh. I only have a headlight LED in the circuit bvut still seems high even for an old Kato.

Agreed. You have an issue somewhere. 770 is too high. Did you try cleaning up the commutator and brushes?

ON28:
Yes, another teardown. Along with drilling holes for grabirons, my favorite part of the hobby!  Any tips for cleaning the comm/brushes? Thanks!

KiloWhiskey:
Just for my curiosity,  how are the power from the trucks routed to the LM? Is it like the newer Kato with hard wires? Can you post pictures of insides?

Thx
Kevin
